I just picked up one of these cheap, but it didn't come with the AC power adapter. So I have a few questions for anyone who has one.

The manual says 12v 500mA - AC

I guess that means I need an AC->AC adapter, is that correct? (not the typical AC->DC adapter that is used more often here in the U.S.). If anyone has one, could you look on the AC adapter and tell me if it says AC on the "output" spec? Thanks.

I know I can get one at RadioShack, and those come with the interchangeable tips to match the size and +/- tip and ring values. So my next question is, when using a device that accepts AC input, will the positive/negative values of the tip/ring on the connector matter at all? And if it does matter, does it give this info on your original VF11 power supply?

I found the right adapter at Radio Shack today and it works perfectly.It does not have an interchangeable tip, but luckily it is the right size for the VF11.Here is a link, in case anyone else ever needs one (Catalog # 273-1631):

First impression: it's awesome! I only played around with it for about 10 minutes, using my Nord Lead and an SM57 mic.It sounds great. I'll try to post some sound clips within the next couple of weeks.

With a good basic sound source (analog poly synth, or even better a string machine), you can achieve very correct vocoded sounds. It doesn't have that vibe that a VP-330 have. And is not so detailled like an EMS vocoder. It's an entry level vocoder, but you can tweak it very easily. Much more than most VA integrated vocoders...

It is much easier to be a good equipment purchaser than to be a great musician.
